rodi hookup diagram?

Hey guys i recently added a booster pump and a second RO membrane to my rodi filter setup, the product water has increased production correctly, but my ASO is not working properly at all, i cant seem to find a hookup diagram online with dual membranes, ASO /w float, and booster pump. I assume i have my ASO valve in the wrong spot on the lines and this is why its not working properly at the moment.

if anyone could give me some guidance as to where exactly the ASO valve has to go in relation to the booster pump and ro membranes it would be greatly appreciated.

right now I have my water line coming into my sediment and carbon filters, then to the booster pump, into the RO membranes, then through a series of twists and turns through the ASO then to di and to my container.

i know originally before i had the check valve, i had called spectrapure and they had me re-arrange it so the ASO would work correctly, and i assume where it is now is the issue since i properly added the needed check valve now. I already reached out to them earlier and hope they call soon but i was hoping maybe someone would have better luck at finding me the diagram i need to set this up properly.

thanks in advance for any help guys!
 
aso should be after your booster pump before RO

like that^^^except you have both post RO lines Teed together right? maybe you need a checkvalve after each membrane...?....any pics?

i have both product lines T'd to one product line, directly into a straight check valve. before it goes into the ASO.

I can't imagine 2 check valves off each membrane would be different than 1 check valve 2 inches further down the line. its still preventing back pressure no matter 1 or 2 valves, its just to keep water from going backward through the membrane.
 
well all brs dual membranes each have their own check valve:strange:... you should try using two valves see what happens......

they only do that for convenience, as if you dont use an ASO you dont need the check valve at all. its just a $2.99 elbow they add in to save headaches. it should be no different than in inline check valve what so ever. where the check valve is shouldn't matter as long as water isn't allowed to flow back into the membrane. If someone in the know 100% can chime in and say otherwise, i'll gladly purchase another one, but I'm pretty sure i shouldn't need a second one. even right in spectrapure's diagrams they have 2 membranes with 1 check valve after the T same as i have it now.


I have moved the ASO part to where it should be in the line now and rerouted all my hose, I'm waiting on UPS to deliver my brs package with my membrane housing clips and another fitting, then i can cut everything to fit correctly and i will test and report back, i'll also throw up a before and after picture of how i had my routing.

The before routing was a huge rats nest and i wanted to redo it anyway. lol


let me reiterate here, before i purchased a check valve, spectrapure had me move the location of the ASO valve to work properly without the check valve, which is why i assume it stopped working after i moved lines and added the booster pump and check valve in. So I'm hoping now with the links/pics from above i have it properly set up.

thanks for all the help :)

Here is the image i use to set mine up...

Thou i have two pre filters two carbon dual membrane and dual di resin ...
 
well, right now i have the ASO valve after the booster pump, and nothing shuts off when the product line is blocked off. so something is still not correct.

i run through 2 sediments, and then 2 carbon blocks myself.

heres a picture of the setup as it sits right now:



not pictured is the dual stage DI cannisters, but that doesnt really change the ASO valve operation so no real need to show that.

only other thing i can try is putting the ASO before the booster pump? not sure if that will make a difference.

The aso works by back pressure from the float switch at the end of the Clean water output.. I Do not have a booster pump in the equation but it takes sometimes 10 minutes to stop the drain line from producing waste water my system has 80 psi water source from local water company..

Also unless you connect them differently with a booster pump that looks configured wrong according to how mine is ..

my input goes into micron filters then carbon filters then to the input of the bottom (screws up) on the aso.. the output of the aso goes into the membranes.
the output of the member clean water to the in on the top of the aso. the output into my first di chamber.. the output of the second di goes into float switch in the di water holding tank

just as it shows in the diagram i posted above.. the booster should be on the supply line first is what i always thought ...

so are you saying my ASO is upside down? I thought maybe that would be the case, ive seen 3 separate walk-throughs where 2 of them had different ways to identify the " top " of the aso.

it goes from my sediments&carbon --> booster pump to the in on ASO, then the out of the ASO goes to the RO, then the product water from RO goes into the opposite in on the ASO and out the other end of the ASO to my DI canisters. i have added a few valves for making straight RO drinking water and whatnot that makes it a little complicated, the white line going down is to DI, the blue going down is for when i want to switch to straight RO.

Actually looking at my Diagram i posted you are exactly the same. The only Difference is your bypass to flush the membrane..
The waste output on my last RO Filter goes to a valve that has a built in 75 gpd re stricter
http://www.bulkreefsupply.com/membrane-flush-valve.html

I Do not have that setup at your waste side with the dual y connectors.. Your aso not stopping might be liked to that or a issue with the restricter but as i said mine takes a good 8-10 min to shut off..

i thought mine was not working properly and i talked to someone on the phone at brs who told me give it 10 minutes.. Your ASO Is correct . I just have no knowledge of where the booster pump goes.. As i have not had to use one.. i assumed it was at the water supply before any filter . I now assume i am incorrect on that part..

Sorry for the confusion.. You could also very well have a defective ASO.. I do NOT Trust them. i always try to remember to shut my whole system off when i leave the house.
 
Correct guys, the green line is spectrapure's 180gpd soft water restrictor.

I will try letting it run longer and see what happens. I was just getting worried after a minute or two because of The booster pump.

The Restrictor should be inside the green line right . a needle size line about 6 inches long for a 75 gpd membrane correct..

is it? do you have your flush valve open in that pic? i think you dont have enough restriction on your waste line.. running dual membranes you need more restriction than one membrane. and because the second membrane is running at lower psi without its own check valve and not enough restriction, i think the first membranes product water is possibly back feeding thru the second membrane product line...and thus not building pressure to activate the aso....i would get one of thesehttp://www.bulkreefsupply.com/membrane-flush-valve.html
400ml.. and get a checkvalve per membrane then T then aso.IMO

there is a restrictor in place already made for dual membranes, directly from spectrapure already installed, its in the green section. its made specifically for dual membrane use.

i will test letting it run longer tomorrow to see if it shuts off, im about to head off to work here shortly.

the picture is of while the unit was sitting unused, so the flush valve in the picture is open.

i am getting ~144gpd out of the dual membranes at 80 psi now. and my city water is terrible so i'm quite okay with that, prior to this it was taking me all night to fill my 30g barrel.

i believe the membranes themselves are working properly. I will be calling spectra pure tomorrow, they will usually walk you through the setup over the phone.
if anyone else sees anything that stands out let me know.
